This is a theory pointing out that Jenna Marshall was the other/true Red Coat. I believe she was on the A-Team since Charlotte’s rise as Big “A”, and I believe Sara Harvey was only a decoy like Charlotte stated.
First of all, I am going to start with the fact that Jenna went to Noel Kahn’s Halloween party in 2x13 (”The First Secret”; the prequel episode) as Lady Gaga… in a red, hooded outfit. You may think that it means nothing, but nothing is really a coincidence in Rosewood. Foreshadowing much?
At that party, she met Mona and they befriended each other, becoming friends seemingly. This, to me, says it all. This is when Mona knew she could turn Jenna against Alison.
I’d also like to point out that Jenna usually wears ‘Jungle Red’ lipstick. I am assuming it is her favorite color. After all, it was Alison’s signature color too.
Jenna was working in two different divisions, and in both, she tried to take down the Liars—the “A-Team” and “Melissa’s Alliance” (with Shana). When we saw Jenna with Melissa and Shana in 3x24 (”A dAngerous gAme”) while Charlotte was plotting against the Liars at the lodge, Charlotte had to bring in a decoy Red Coat… which was Sara Harvey. Jenna and Sara never met though until Season 7 when they knew they both assisted Charlotte in her gAme.
No one other than Jenna has had a stronger reason to hate the Liars. They BLINDED her! I’d be pretty pissed too, even if it was an accident. Jenna came to Rosewood as the new girl who just wanted to make friends. Alison, being the bitch she was, decided to instantly hate Jenna only because she turned down her offer to join her group (the Liars). Yes, Jenna may have sorta forced her step-brother into relations with her, but that was an mistake. Like Jenna says, “We all make mistakes that we’re not proud of.”
Jenna turned into the way she is today because of Alison and the Liars. THEY damaged her! She didn’t do it to herself. She couldn’t forgive them for what they did to her. And to think they’ve still gotten away with it disgusts me a little. Since then, Jenna has wanted revenge. She became Red Coat and assisted Charlotte to take them down.
Remember Emily’s disappearance in 3x01 (”It Happened ‘That Night’”), and that Jenna had “rescued” her? She didn’t rescue her. Jenna was there that night digging up Alison’s grave with Charlotte. Jenna claimed she had found Emily drunk and lonely, so she put her in the car. Emily didn’t remember anything that happened that night until it slowly came back to her. She recalled being in Jenna’s car… and Jenna was wearing, somewhat, a red coat!
Jenna was seen putting her hair up while driving the car, but why? Because she was wearing a blonde wig as RC!
In 4x01 (”’A’ is for A-l-i-v-e”), we see Jenna going to Wilden’s funeral with a man named Nigel. Later on in 4x07 (”Crash and Burn, Girl!”), Toby and Caleb go to see Nigel for answers towards the “girl in the red coat”. Nigel claims he was paid by CeCe Drake, who is Charlotte. Who says he wasn’t protecting Jenna by revealing her partner’s identity instead of hers?
He was later seen having a drink with a girl he called “babe”, who I think was Jenna. There were dark glasses sitting on the table, hinting towards it being Jenna. Toby and Caleb found out he was the pilot of the plane Red Coat was seen getting off of at the lodge fire. The lodge fire makes perfect sense when it comes to Jenna. The Liars blinded her with a stink bomb that started a fire. Maybe Jenna wanted the same to happen to them?
In 3x24, the episode that has the lodge fire incident, we see “A” sending Jenna a message, saying: “32 Rte 6. Be there at 9 tonight. -A”. Was Charlotte telling her where to go?
I found something quite convincing. When I. Marlene King was responding to a fan regarding Red Coat on Twitter back in 2013, she said this:
Jenna could easily walk in heels like that when she was supposedly turning blind again, and possibly run in them, as shown in 3x24:
Jenna is a great liar. She’s a master at lying like Charlotte. We now know that they were good friends, but Shana revealed to Spencer in 4x09 (”Into the Deep”) that Jenna was afraid of CeCe/Charlotte. What if this was a cover-up? We know that Nigel protected Jenna, so Shana probably did too. Or maybe Jenna was afraid of Charlotte because she knew her intentions and what she was capable of, yet she still played the game with her. Marlene said that Charlotte was the one who hit Jenna and left her to drown in 4x09. I believe this wasn’t true. It was another cover-up. It also doesn’t make sense with the timeline now that we know Charlotte and Jenna were friends.
Jenna was Red Coat most of the time and the only time Charlotte was Red Coat was in 4x12 (”Now You See Me, Now You Don’t”) when she was used as a decoy to distract the Liars from Alison, and also when Red Coat crept into the DiLaurentis home and snuck into the basement. Those were the only times she was Red Coat. The rest was Jenna. Sara was only Red Coat when Charlotte needed her to be. She was a decoy like she said she was. Charlotte protected Jenna. We know that Jenna is working with A.D. to bring down the Liars, and she wants to find Charlotte’s killer. She was definitely good friends with her and working with her at some point if she wasn’t Red Coat.
I’d like to point out that Red Coat started appearing when Jenna got her sight back, and then disappeared again when Jenna lost her sight. Coincidence? We saw Wren in 4x10 (”The Mirror Has Three Faces”) coloring in a red coat onto his picture of a long-haired brunette. Many fans have suspected Wren of being involved with the A-Team. Was this hinting towards Jenna being RC? Maybe he knew?
I could go on and on, but I believe Jenna was always the real Red Coat. She is endgame.
